LP2989IMX-5.0/NOPB

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The LP2989IMX-5.0/NOPB is a fixed-output linear low-dropout regulator manufactured by Texas Instruments, designed for positive voltage regulation applications. It delivers a maximum output current of 500 mA with a fixed output voltage of 5 V. The device supports an input voltage range up to 16 V and features a typical dropout voltage of 310 mV at full load. It incorporates internal protection mechanisms including overcurrent limiting, thermal shutdown, and short-circuit protection. The component operates within an extended temperature range from -40°C to +125°C and is housed in an 8-SOIC surface-mount package.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Provides stable fixed 5 V output with 500 mA continuous current capability
• Integrates comprehensive protection against overcurrent, thermal overload, and short circuits
• Operates reliably across industrial temperature ranges from -40°C to +125°C

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Applications

• Battery-powered portable electronic devices requiring efficient voltage regulation
• Embedded systems needing clean power supplies for sensitive logic components
• Industrial control modules operating in harsh environmental conditions

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the complete part number LP2989IMX-5.0/NOPB matches your design requirements before ordering. Confirm that the 8-SOIC package dimensions align with your PCB footprint specifications. Ensure the 5 V fixed output meets your system's voltage needs. Check that the 500 mA current rating suffices for peak loads. Validate compatibility with your input voltage source which must not exceed 16 V.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a fixed 5 V supply is required with moderate current demands up to 500 mA. It is suitable for designs prioritizing simplicity and built-in protection over adjustable output flexibility. Consider the 8-SOIC package if space constraints allow for standard surface-mount assembly. Evaluate the 16 V maximum input limit to ensure it covers your highest expected supply voltage scenarios safely.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This regulator belongs to the LP2989 series of micropower LDOs from Texas Instruments. The series offers various output voltages and packages, including SOIC, WSON, and VSSOP options. The 'IMX' suffix indicates the industrial temperature grade and SOIC-8 tape-and-reel packaging. The '/NOPB' designation confirms compliance with RoHS standards and absence of lead-based materials.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

LP2989AIMX-5.0/NOPB is a verified alternative offering identical electrical characteristics in the same 8-SOIC package. LP2989ILD-5.0/NOPB provides similar performance but utilizes a WSON-8 package, requiring PCB layout adjustments. Verify pinout compatibility and thermal dissipation requirements when substituting these parts.
